8.75 bearing install and assembly tips

I press the cones on. As for the races, some are easy to get to (the front one) and I usually use a socket to drive them in. For the back one that's recessed I have some long hardened 1/2" round rod that I use to tap them in with. Races are generally easy to drive in

I ran into one instance while doing a Ford 9" where things were super tight so I heated the bearings to 200* in the oven and froze the pinion to get them to press on. I think as long as you heat bearings evenly such as in an oven and don't go over 300* you won't hurt anything. Heating them with a torch can cause hot spots that easily exceed 300* and make for a weak spot that can fail later
